A Application led September This invention relates toa hoisting apparatus. The form' illustrated herewith is particularly adapted for use in handlin coal .or cinders in connection with railroa s, although it is not limited to that use. One

object of the invention is to provide a simple andcompact device `wherein a tippin bucket may bevmoved into and out of an above a receiving bucket, and may be so l0 moved along two or more inclines of different degrees 'of inclination. Another object is to provide in connection with such apparatus means whereby such bucket may be moved-and held at all times inupright po# I5 sition withoutthe necessity of complicated supporting mechanisms andwithout the use of rigid bails or additional moving' parts. Other objects will appear from time to rtime throughout the specllication and claims.

My invention is illustrated more or less diagrammatically Jin the accompanying drawings, wherein:

Figure 1 is an elevation with parts in sec-v tion showing the device installed in connection with a railroad;

Figure 2 is a section on an enlarget showing in greater detail the pit and of Figure 1;

Figure 3 isa detailed'perspective showing a portion of the track within the pit;

Figure 4 is a vertical cross section taken on line 4 4 of Figure 2;

Figure 5 is a partial vertical cross section illustrating a gate Figure 46 isasplan view with t-ion showing the same; Figure '7 is a section on line 7-7 of Figure 6.

Like parts are indicated by like characters 0 throughout.

A is a track upon which a locomotive A1 may be positioned and may move. B is a track which may be parallel Vto the track A;

The arrangement herewith constitutes 'a 5 cinder plant that is'a receiving and dumping mechanism for' receiving cinders and ashes `from a` locomotive and for raising and dump-l ingthe same into a car or other receptacle adapted-.to carry them away.I

C is a receivingpit having walls C1 and a receiving chute C2 whichsmay be formed as apart of the pit or as here shown by the use of additional parts. C-3 is a well adapt scale ucket 5 parts in secedv to receivevttr or other liquid whiclfmay lpoint wlmre it is joined to the track D1 and is 110 5 'bedrawnin'tofth'e' pit to concentrate the same,

as, 192s. serial nn.- lames.

the track Dl'whicli rests on the bottom of the pit C. D4 is a. guide track'located Aadjacent the upper endof 'the track D1 lying generally 'I0 parallel to the main portion. D is a later'v ally bent extension ofthe ide track D1. It is so'bent to cause the buc et D to tip andi empty its'contents in tipping. D is an ex' tension from the frame D2 to which the u per 75 end of the track D4 and the outer end o the I laterally bent'l portion D* are joined.v D7 is a guide track parallel to the track D* and forming with it'a guidin and tippin niember.l DB is a'chute into w ich the buc et dis- 80 charges at the upper end of' its excursion i when tipped. D is a. hoisting cable and D1 is a hoisting means located ait/the upper end lof the lower or framework D1. This hoisting means may be of any suitable type adapte to draw in Vthel cable and to raise the bucket.. The'details of'it form no particular part4 of the present invention.

E -E are Banged rollers, one of which Ais mounted on each `side of the bucket. Gener- 9o ally similar rollers'E1 E1 are located one on eachside of the-bucket,v but'these rollers. have wider ianges than those of the rollers` E. E1 is an angle or bail contacting member.

ATwo of these members are mounted upon the Y y bucket, one on each side. When the bucket is in the lower position as shown'particularly in Figure 2 the exible t ese angle members E2.

Fastened to the bucket and prefer the shaft which'carries the rollers E is a exible bail E3. Thisl bail may be as 'shown' formed of a cable.'V At its upper end itincludes a rigid cross member E4. to which the side members of the bail are fast ned, and it has mounted preferably adjacent its center a shave E5. E6 E are rollers mounted at the outer ends of the shaft E4. T)

The guide track D3 is narrowed at the detail in Fi ure 3. 0`6 I bail is bent about ablV to 10o A l generall provided with' cut away portion E. Situated above 'the guidetrack D isa second guide track provided with an Vupward inclined arm Ea and a lower arm-E which is (parallel to the guide track D3. It 1s provi e at its. upper end with an-upwardly bent portion E10 which is generally parallel to the more steeply inclined part of the track D1. E11 E11 are braces mounted about the open pit mouth and forminga support for the upper arms E E8? 1 X is a car standing on the track B and receiving a load, for example, of cinders X1.

Although I have shown an operative device, still it will be obvious that many changes might be made in size shape and arrangement of parts without departing materially from the spirit `of m invention; andI wish, therefore, that my showing be taken as in a sense diagrammatic.

In Figures 5 and 6 I have shown a gate adapted to close the receiving pit opening. This gate has b'een omitted from Figures 1 and 3 in order to avoid confusionr and be,l cause it is not always used. It may be inserted," however, and usually is Inserted in an installation of the sort shown in the' main igures.

which rest upon the tracks G and by means of F is a portion of the pit, cover. As here shown it is made of concrete. Located within the pit, preferably, at an incline are tracks G G. These tracks are fastened to the -walls C1 of the pit by means of supports G1 G1.

' H isa gate provided with rollers H1 H1 which the gate is mounted sopas to move freely -along the track.

I isa shaft. supported in bearings 1 I1 provided with a gear I2 having .fixed upon'it a .crank arm I. I4' is a connecting arm or lever pivotally mounted at one end' of the bearing Il5 on the gate H and pivotally connected at its other end to the arm I3.

J is a stub shaft mounted in bearings J1 J 1 carrying at o ne end agear J whichem'eshes with the gear I1. J 3 is a lever arm mounted on the shaft J extending lupwardly through an opening J 1 in the member'F.

In Figures 6 and 7 particularly there is illustrated in detail the clutch mechanism u which is used where two gates for two recelving buckets are to be operated from the same gate controlling mechanism. .One gate alone may be used as shown in Figure 5 and in that case the selective clutch mechanism shown in Figures 6 and 7 is not necessary, although it may be used.l Where two gates are used, this clutch mechanism'becomes necessary. When 4the clutch mechanism is used' the lever arm P is'fastened to a slidablecollar K which is.k provided with a notched end K1- and i's 'mounted for rot-ation relative to the shaft I. A similar collar L is provided with a notched face L1 and is mounte'd on the shaft andA pro'-v vided with a short lever arm L similar to the arm I3 which is joined to aconnecting rod or arm L. n Y

The shaft I is provided with two separated keys not shown in detail. Mounted on the shaft and provided with key-ways ada tedV to engage the keys, are twoA clutch mem rs M-M1. lllacllaof these membelrs hals1 fstellied toita oe zMr ctive w'c o are joiried together opeyrliting roll 5 which is slidably supported in bearings M5 and provided with a projection M. Each of the members M M1 has notches on its inner face as shown and they may engage respectively the notches K1'L1. Y

N is an operating tumbler pivotally Vsupported as shown and provided with projecting jaws N1 adapted to engage the projection M". N2 is an operating handle pivotally mounted at N 3 upon the tumbler N for limited movement with relation thereto. N1 Y and N5 are extended contact faces 'of the tumbler N adapted to be contacted by a porvtion ofthe handle Nz-- N6 is a weight on the handle N2.

so as to throwinto or out of operation one or the other gate. As shown in`Figure 7 Ythe right hand member L is in mesh with the. clutch member M1 and when the parts are -in this position it will be the member L which will rotate with the shaft I and the rod L3 which will move to open or close the gate to which it is attached. -l

. If it is desired to move the other gate the handle N2 will be rotated. At rst it will move with relation to the tumbler N and Vcause no movement of the tumbler. When it In operation the clutch mechanism is used contacts the face N4 it can have no :furtherl movement with relation to the tumbler N and thereafter raises the tumbler with it for a brief distance, moving the clutch member N1 outof engagement with the teeth L1 of the member L andmovin the clutch member M into engagement witg the teeth K1 Yof 'the member K, to which the lever Itis attached. With the parts then'in this position, if the lever.v J 1 did raise, it would move the lever I, the rod K* and the gate H;

The use and operation of my invention are track D3 and are diverted upon the track D1 thus retaining the bucket in its upright position withoutV tiltin it from. theV position which' itloccupied w en it was supported upa ,on the t kir alone before iteaaredfhe pit.

f As the ucket movesxlownward, the rollers on the rigid cross member of the bail strike the arms Es or E9 and are finally retained at `the pointof juncture of these arms as shown 1n Figure 2. When' they' occupy this posit1on, the cable o r yielding portion of the bail is .bent as shown over the members E2. Thus even if the hoisting cable` should break or should be allowed to become loose, the-.bucket will be retained of itself in anv upright posi- I tion.- It cannot jam or slide 0E thetrack or became displaced as a result of damage to the hoisting mechanism or as a result of unsatisfactory' orJ incomplete operation of the hoist ing mechanism or ,anyD part of it. After the bucket has reached the position shown in the bottom of the pit, cinders are,deposited into up by the hoisting apparatus at the top of the tower. `The upper rollers move a v onto the main track and the rigid cross ail it from a'loeomotive or from some othersource and the main hoisting cable is drawn member moves upward until it occupies the plesition shown indotted lines in Figure 2. this posltlon it will be noted that the hoisting effect of the bucket'I is exerted on the shaft which carries thetwo lower rollers E.

A s vthe bucketjis v.drawn upward and ap l, preaches the upper limit of its excursion, the

'up'per rollers, that is the large Banged rollers E1 move outward along thetrack D5. Since the hoistin fthe shat will be lin the closed position shown in Figure 5. In that position the handle or lever I J 3 is in the down position. When it is desired to', openl .the gate, this handleV is' raised and s 'i through the gears the gear I isl caused to rotate in a counterl clock-wise direction as viewed in Figure 5, .the crank arm Is-.moving with it into the dotted linelpositio'n as shown in Figure 5, and this movement through the `connecting member I is trans-v f mitted to the .gate whichis moved outofpo'- sition in the' openin of the pit into the'n dotted line positlon w ereby the pit opening is left free and availableor material.

In Figures `5, 6.an'd 7, there is shown the gate mentioned in the preceding paragraph. There is also shown a clutch mechanism.: This mechanism is not always necessary where only a single gate is used but whe e two gates are to be usedtogether, contro ling the cpenings 'to two fpits, or to one pit having two openin as is"shown .1n Flgures and 7, it ispre erble to use the clutch.

into and from such l'movement of such By this means with one operating vhandle and one operating mechanismit is-possible-`v lto .control two gates separately-'and .open

them one at a time. I have shown in Figure 7, the "operating part L as in engagement with the member M1 and the gate controlled by the lever Ls will be operated when the handle J a is moved .from ,the position it oc- To alter this operation the handle M2 ismoved from the 75 position shown in'Fi ure 7 over toward the eft in a counter cloc wise direction. Thus the member L is disengaged, the member 'K becomes engagedwith the member`M and the handle J 3 is then moved from the posi- .80

tion which it occupies to the vertieal, the

operating rod I4 will be moved and the gate H which it controls will be correspondingly moved. i
